Maximizing the Efficiency of Your Combustion Process

Oxyfuel combustion can make a valuable contribution to improving the carbon balance of fossil fuel combustion. With this process, coal is combusted in an atmosphere consisting of pure oxygen and carbon dioxide (CO2). This purer mixture burns at a higher temperature than natural air, thus increasing the efficiency of the combustion process.

Additionally, the resultant flue gas is not diluted by nitrogen normally present in air, but primarily consists of CO2 and water vapor. The flue gas stream is therefore smaller and easier to handle.

This vapor is easily condensable, leaving a highly concentrated CO2 stream. The CO2 can then be compressed and stored.
